Wide range of applications in systems installation and maintenance, as well as production
The OLA-15 Optical Attenuator is a handy-sized, rugged instrument for variably attenuating optical signals in single-mode applications at 1310 and 1550 nm. Example applications include the simulation of line loss for BER tests on fiber optics systems, the determination of system margin / receiver sensitivity or the calibration of optical power meters. A complete test set comprising signal source, attenuator and power meter contained in a shock-resistant case is also available.

Large, continuously variable attenuation range
The large rotary control on the front panel is used to set attenuation quickly and simply within a wide range between 3 and 60 dB. The optical path is not interrupted when the attenuation is altered. As the OLA-15 is bidirectional, the instrument is very easy to use.

Attenuation settings highly accurate and reproducible
Reliable measurements demand accuracy and reproducibility of the attenuation setting. Each instrument is individually calibrated, guaranteeing that every OLA-15 meets this requirement. Careful design of the optical components ensures interference-free attenuation settings over the entire temperature range. The attenuation setting is indicated on a large liquid-crystal display.

High return loss
The OLA-15 is also suitable for measurements on systems sensitive to back-reflection, e.g. those operating at high bit rates. The return loss (reflection attenuation) of more than 40 dB means that the OLA-15 can be looped into the signal path without problems and without affecting the transmission characteristics.

Universal interchangeable adapter system
The universal system of interchangeable adapters allows matching to all commonly-used fiber optics connector systems, such as FC, SC and DIN. It also ensures easy access to the instrument's internal connectors for the purposes of cleaning and inspection. Special dust caps protect the optical connectors from dirt and damage.

Rugged shock and water-resistant casing
The instrument is protected against shocks and wear and tear by a well-designed, non-slip, robust casing, giving the OLA-15 the mechanical ruggedness required for field use under often difficult ambient conditions. The foil keypad gives protection against dripping water. A fold-out instrument stand is located on the back panel.

AC line or long-life battery operation
The Optical Attenuator is designed for use with dry batteries or with NiCd cells. Typical operating time from dry batteries is 45 hours; a set of NiCd cells will run for typically 15 hours, more than a day of uninterrupted operation. When a separate AC adapter is used, the instrument can be AC powered and NiCd batteries fitted in the instrument can also be recharged.
